Janet Yellen: Financial Stability a Decade After the Onset of the Crisis

A decade has passed since the beginnings of a global financial crisis that resulted in the most severe financial panic and largest contraction in economic activity in the United States since the Great Depression. Already, for some, memories of this experience may be fading — memories of just how costly the financial crisis was and of why certain steps were taken in response. Today I will look back at the crisis and discuss the reforms policymakers in the United States and around the world have made to improve financial regulation to limit both the probability and the adverse consequences of future financial crises.

A resilient financial system is critical to a dynamic global economy — the subject of this conference. A well-functioning financial system facilitates productive investment and new business formation and helps new and existing businesses weather the ups and downs of the business cycle. Prudent borrowing enables households to improve their standard of living by purchasing a home, investing in education, or starting a business. Because of the reforms that strengthened our financial system, and with support from monetary and other policies, credit is available on good terms, and lending has advanced broadly in line with economic activity in recent years, contributing to today's strong economy.1

At the same time, reforms have boosted the resilience of the financial system. Banks are safer. The risk of runs owing to maturity transformation is reduced. Efforts to enhance the resolvability of systemic firms have promoted market discipline and reduced the problem of too-big-to-fail. And a system is in place to more effectively monitor and address risks that arise outside the regulatory perimeter.

Nonetheless, the scope and complexity of financial regulatory reforms demand that policymakers and researchers remain alert to both areas for improvement and unexpected side effects. The Federal Reserve is committed to continuing to evaluate the effects of regulation on financial stability and on the broader economy and to making appropriate adjustments.

I will start by reviewing where we were 10 years ago. I will then walk through some key reforms our country has put in place to diminish the chances of another severe crisis and limit damage during times of financial instability. After reviewing these steps, I will summarize indicators and research that show the improved resilience of the US financial system — resilience that is due importantly to regulatory reform as well as actions taken by the private sector. I will then turn to the evidence regarding how financial regulatory reform has affected economic growth, credit availability, and market liquidity.

The US and global financial system was in a dangerous place 10 years ago. US house prices had peaked in 2006, and strains in the subprime mortgage market grew acute over the first half of 2007.2 By August, liquidity in money markets had deteriorated enough to require the Federal Reserve to take steps to support it.3 And yet the discussion here at Jackson Hole in August 2007, with a few notable exceptions, was fairly optimistic about the possible economic fallout from the stresses apparent in the financial system.4

As we now know, the deterioration of liquidity and solvency within the financial sector continued over the next 13 months. Accumulating strains across the financial system, including the collapse of Bear Stearns in March 2008, made it clear that vulnerabilities had risen across the system. As a result, policymakers took extraordinary measures: The Federal Open Market Committee (FOMC) sharply cut the federal funds rate, and the Federal Reserve, in coordination with the Treasury Department and other agencies, extended liquidity facilities beyond the traditional banking sector, applying to the modern structure of US money markets the dictum of Walter Bagehot, conceived in the 19th century, to lend freely against good collateral at a penalty rate.5 Still, the deterioration in the financial sector continued, with Fannie Mae and Freddie Mac failing in early September.6
